OIL BURNER.

Application filed November 9, 1926. Serial No. 147,286.

This invention relates to new and useful improvements in oil burners, and has for itsprimary object to provide a burner that is of such a construction as to overcome the requirement of an air or steam blast, the

same requiring only a natural draft for its successful operation. I

A further and important object is to provide a burner of this character that is of extremely simple construction and one that may be arranged within a furnace in a simple andconvenient manner without requiring any unusual alteration of the furnace.

Other objects will become apparent as the nature of the invention is better understood, the same comprising the novel form, combination, and arrangement of parts hereinafter more fully described, shown in the accompanyingdrawing and claimed.

In the drawing wherein like reference characters indicate corresponding parts throughout the several views:

Figufe 1,is a top plan view of a burner constructed in accordance with the present invention.

Figure 2 is a side elevation thereof.

Figure 3 is a longitudinal vertical section, and

Figures 4 and 5 are vertical transverse sections taken substantially upon the lines 4-4 and 55 respectively of Figure 2.

Now having particular reference to the drawing wherein thereiis disclosed the pre-,

ferred embodiment of the invention with which I am at this time familiar, the burner consists of an elongated rectangular shaped oil pan 5, the bottom wall of which is formed longitudinally with a narrow elongated slot 6 from the edges of Which'arise upstanding flanges 7 that extend above the side walls of the pan 5. The extreme upper edges of the flanges that surround said elongated slot converge inwardly so as to produce arestricted longitudinal orifice 8 that in reality forms an air nozzle, through which escapes the natural draft that passes upwardly through the slot in the bottom wall of the pan.

Interconnecting one end wall of the pan 5 and the adjacent end flange surrounding the slot 6 is a boss 9 that has a central bore 10 therein that registers with a larger socket 11 in the outer Wall of the said end of the said pan 5 for receiving one end of an oil supply pipe 12. Projecting laterally from the bore 10 in said boss 9 at opposite sides thereof are oil openings 1313 for permitting the oil conveyed by the pipe 12 to pass into the pan 5 at opposite sides of the upstanding flanges surrounding the elongated slot 6 of said pan.

It will be obvious that the burning of theoil in the pan 5 will cause the flame to creep up the outer surfaces of the flanges sur rounding the slot 6 in the pan and that sufficient draft will be provided by the air escaping through the nozzle 8 so that the proper combustion will take place.

Even though I have herein shown and described the invention as of a certain structural formation, it is nevertheless to "beunderstood that some changes may be made in th form of the invention without departing from the spirit and scope of the appended claim.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is An oil burner of the class described comprising a relativi y elongated rectangular shaped oil pan having an elongated slot extending longitudinally through the bottom wall thereof, upstanding flanges at the edges of the slot extending above the upper edges of the side and end walls of the pan, the upper edges of the upstanding flanges converging inwardly to provide an air discharge nozzle, and means for facilitating the introduction of oil into the pan around the upstanding flanges comprisinga boss interconnecting one end of the pan ia'nd the adjacent end of the upstanding-flanges, said end wall being provided with a socket, a fiiel piply pipe fitted at one end in said socket, sai boss being formed with a passage, which communicates at one end with the socket, said boss being formed with an ad ditional passage disposed transversely to the aforementioned passage and communicating therewith for elivering the fuel into the pan from opposit sides of the boss.

In testimony whereof I aflix my signature,

THOMAS H. KELLY.-
